In this video, I show you how to build your own AI UGC ads web app without writing a single line of code. We use Lovable to spin up a simple landing page + dashboard, then connect it to Google DeepMind’s Veo 3.1 (V3.1) through Key.ai so we can generate UGC-style videos from a single image and a prompt. The whole goal is: user uploads an image (and your product image concept), writes a prompt, picks aspect ratio/model, hits “Generate,” and gets a video back—fast. On the backend, I wire everything with n8n using a webhook that receives the form data from Lovable. Then I upload the image to Google Drive to get a public URL, send the prompt + image URL to Key.ai’s API, wait about 60 seconds, check the task status, and return the final video URL back to the app. I also show a real test where I turn an Adidas shoe image into a vertical UGC ad, and the result is honestly impressive—even with a simple prompt. If you’ve been wanting to build an AI-powered creative studio or ad generator you can monetize, this is the exact workflow to start with.
